CRT_Emudriver / RetroARCH issues

[nipsmg]

Hey guys, I'm hoping someone can help me out.   -- I know this is a GroovyMAME forum but you guys are all using CRT_Emudriver so...

I've got an HD4350 (legacy) working .

I'm having an issue with RetroArch where it's displaying stretched, like super resolutions aren't working.



I followed this guide: https://cdcruze.com/2019/03/retroarch-and-crt-emudriver-setup-guide/  , and read a bunch of reddit/forum posts, tried integer scaling on, no dice.

I've attached my config file.  Any help is hugely appreciated.

Thanks!

RA..

Nah, seriously. The best way to configure properly is configure every system with their resolution; and obviously you need installed modelines in your videocard previously.

For example, for bluemsx core i have this config.

crt_switch_resolution_super = "native"

video_aspect_ratio = "8.000000"
video_refresh_rate = "60.00000"
video_rotation = "0"
video_scale = "1.000000"
video_scale_integer = "false"
video_smooth = "false"
video_crop_overscan = "false"
video_threaded = "false"

aspect_ratio_index = "23"
custom_viewport_height = "240"
custom_viewport_width = "272"
custom_viewport_x = "0"
custom_viewport_y = "0"

I HATE retroarch.  Seriously.  With a passion.  But it seemed to have a lot of tutorials for 240p so I went for it.

Another example using 1920 super resolution for Sega Genesis. In this case, i used 1920 for match refresh_rate with modeline, and i reserved 2560 for 60hz.

Another tip is split config files for system: retroarch.exe -L %fullpath%cores\genesis_plus_gx_libretro.dll --config %fullpath%config\retroarchcustom.cfg --appendconfig %fullpath%config\genesis.cfg %1

crt_switch_resolution_super = "1920"

video_aspect_ratio = "8.000000"
video_refresh_rate = "59.922745"
video_rotation = "0"
video_scale = "1.000000"
video_scale_integer = "false"
video_smooth = "false"
video_crop_overscan = "false"
video_threaded = "false"

aspect_ratio_index = "23"
custom_viewport_height = "224"
custom_viewport_width = "1920"
custom_viewport_x = "0"
custom_viewport_y = "0"

You may have solved your problem by now. But I had the same issue until I found a setting for 'Full Panel' in Radeon settings under GPU Scaling. The Preserve Aspect Ratio setting resulted in the squashed image for me.

@mamenewb100, how did you install Radeon Settings for your 5450?

[mamenewb100]

I probably wasn't supposed to install any Radeon software? Forgot about that. It was part of the recommend software for the card from ATIs website. I just noticed that the 15Khz resolutions weren't working with the VGA to composite adapter I was using to connect a TV. Just had a scrambled screen. I happened to notice that the scaling option allowed it to work. But it's possible the software could cause conflicts with your drivers?

[Calamity]

No, I was just curious to see what package you used for this! It's been usually difficult to get the Radeon Settings app to install at all with CRT Emudriver.

I believe it's part of the Catalyst Software Suite but could be Crimson Edition. I used Windows 10 Home 64 Bit Edition. It was installed after Calamity drivers but before VMMaker.
